United Equipment Accessories (UEA) offers a wide variety of 2.0”- 4.0” bore slip ring circuits. In addition to our off-the-shelf, existing options listed below, UEA engineers can assist customers by recommending ring material and brush material based on the customer’s specific slip ring applications.

2.0 Amp – The 2.0 Amp circuit uses a “radiused” compact brush assembly and a two-post brush design. The brushes are radiused so that there are four points of extended pressure contact. This circuit option is available with copper or silver graphite brushes and brass or plated silver rings. The voltage option for this circuit is 28V-120V.

7.5 Amp – The 7.5 Amp circuit uses a compact brush assembly and a two-post brush design. This circuit option is available with copper or silver graphite brushes and brass or plated silver rings. The voltage options for this circuit are 28V-1000V.

10-15 Amp – The 10-15 Amp circuit uses a 0.125” wide brush assembly and a two-post brush design. This circuit option is available with copper or silver graphite brushes and brass or plated silver rings. The voltage options for this circuit are 28V-1000V.

20 Amp – The 20 Amp circuit uses a 0.125” wide brush assembly and a two-post brush design. This circuit option is available with copper graphite brushes and brass rings. The voltage options for this circuit are 28V-1000V.

30-45 Amp – The 30-45 Amp circuit uses a 0.25” wide brush assembly and a two-post brush design. This circuit option is available with copper graphite brushes and brass rings. The voltage options for this circuit are 28V-1000V.

50 Amp – The 50 Amp circuit uses a 0.25” wide “extended-length” brush assembly and a two-post brush design. This circuit option is available with copper graphite brushes and brass rings. The voltage options for this circuit are 28V-1000V.

60-80 Amp – The 60-80 Amp circuit uses two 0.25” wide brush assemblies and a two-post brush design. This circuit option is available with copper graphite brushes and brass rings. The voltage options for this circuit are 28V-1000V.

100-120 Amp – The 100-120 Amp circuit uses four 0.25” wide or two 0.375” wide brush assemblies and a two-post brush design. This circuit option is available with copper graphite brushes and brass rings. The voltage options for this circuit are 28V-1000V.

125-150 Amp – The 125-150 Amp circuit uses a 0.50” wide brush assembly and a two-post brush design. This circuit option is available with copper graphite brushes and brass rings. The voltage options for this circuit are 28V-1000V.

200-300 Amp – The 200-300 Amp circuit uses two 0.50” wide brush assemblies and a two-post brush design. This circuit option is available with copper graphite brushes and brass rings. The voltage options for this circuit are 28V-1000V.

400-600 Amp – The 400-600 Amp circuit uses four 0.50” wide brush assemblies and a two-post brush design. This circuit option is available with copper graphite brushes and brass rings. The voltage options for this circuit are 28V-1000V.
